Phenylephrine is a sympathomimetic drug that belongs to the class of alpha-adrenergic agonists. Phenylephrine is a common nasal decongestant that people use to alleviate nasal congestion associated with colds, allergies, or sinusitis. Additionally, it may be employed to raise blood pressure in cases of acute hypotension. It works by stimulating alpha-adrenergic receptors, resulting in vasoconstriction and a reduction in blood vessel dilation, contributing to its decongestant effects.
